However, hydrogen is the lightest element on earth, and the density of hydrogen is very low in both gas and liquid states, and the hydrogen energy is used as a fuel, so that the problems of storage and transportation are needed to be solved. In the development process of the hydrogen energy technology, how to store hydrogen with high density and safety is a key to the actual trend of the hydrogen energy technology.
It is found that to realize large-scale storage and utilization of hydrogen energy, the hydrogen storage system needs to have the following characteristics: high hydrogen storage density, flexible and convenient use requirement, and safe and reliable hydrogen storage mode.

While the present method for storing hydrogen in organic liquid generally adopts a thermocatalytic hydrogen storage mode, the traditional thermocatalytic hydrogen adding method requires that hydrogen is deposited on a substrate with larger surface area (such as alumina, silica or zeolite) and is catalyzed and decomposed by active metals on the substrate such as palladium, platinum, rhodium, ruthenium or Raney nickel, and the like, the reaction conditions are generally severe (the pressure is up to 500atm and the temperature is up to 200 ℃, so that the problems such as expensive reactor design, easiness in thermal decomposition or isomerization of organic substrates at high temperature and the like are caused. In addition, conventional thermocatalytic hydrogenation requires the provision of hydrogen as a hydrogen source, which presents a safety hazard.
